OpenSTA is a distributed software testing architecture designed around CORBA. The current toolset has the capability of performing scripted Web (HTTP and HTTPS) heavy load tests with performance measurements from Win32 platforms.

Usage Notes:

The applications that make up the toolset in OpenSTA were designed specifically for people involved in the testing of software. The tools use a record and play metaphor, similar to many commercial testing products. Testers can make recordings using a browser that produce simple scripts that can in turn be edited and controlled with a special high-level language. Testers can then playback these scripts to simulate many users. Ultimately, you can test your applications under heavy load simulations that mimic hundreds to thousands of virtual users.
